private static final int SELECT_PHOTO = 100;
ImageView image;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    image = (ImageView) findViewById(R.id.imageView2);
}

public void pickAImage(View view) {
    Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
    photoPickerIntent.setType("image/*");
    startActivityForResult(photoPickerIntent, SELECT_PHOTO);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) {
    super.onActivityResult(requestCode, resultCode, imageReturnedIntent);

    switch (requestCode) {
        case SELECT_PHOTO:
            if (resultCode == RESULT_OK) {
                Uri selectedImage = imageReturnedIntent.getData();
                InputStream imageStream = null;

                try {
                    imageStream = getContentResolver().openInputStream(selectedImage);
                } 
                catch (FileNotFoundException e) {
                    e.printStackTrace();
                }

                Bitmap yourSelectedImage = BitmapFactory.decodeStream(imageStream);
                image.setImageURI(selectedImage);// To display selected image in image view
            }
        }
    }
}
